1. INTRODUCTION
1.1 UNIVERGE® 360
Industry analyst research has revealed the top three issues on every executive’s mind –
maintaining a competitive advantage, attracting and retaining customers, and designing
business strategies. Communications companies now have the opportunity to provide these
executives with a way to address these issues. They must put people back in the center of
business communications. They must learn how to take advantage of the convergence of IT
and communications and see how to look forward to a software future which takes into
consideration their investments in people and technology.
We discuss NEC’s UNIVERGE®360, which is NEC’s approach to unifying business
communications. It provides a foundation for understanding the importance of putting people
at the center of communications and reveals how your communications needs determine the
Unified Infrastructure, Unified Communications and Communications Enabled-Business
Processes necessary for a true Unified Business.
1.2 WHAT IS UNIVERGE® SV8500?
The SV8500 is a premier IP Communications server that supports voice, unified
communications and mobility solutions for tens of thousands of users. Designed to easily and
efficiently scale, the SV8500 meets the needs of the largest enterprises, supporting up to
192,000 ports in a networked environment.
The innovative design coupled with flexible Licensing controls allows a system to expand
easily and grow smoothly. The versatile architecture accommodates the widest possible
variety of services, and supports customization to suit your organizations unique needs.
Most importantly, the UNIVERGE® SV8500 offers customers a flexible, telephony platform
from pure IP to converged hybrid for a solution deployment to support their whole
organization.
The UNIVERGE® SV8500 solution consists of the following items: The SV8500 as a 19” Rack mountable 3RU server. This hardware platform utilizes
an industry standard Intel processor and is powered directly from AC100-240-volts
or DC-48-volts. This server controls the features and licensing options for the
system in addition to the Processor for managing communications between SIP
devices, TDM devices and NEC’s extended SIP terminals as IP Peer-to-Peer.
 In addition to the SV8500 servers, a range of distributed IP media converters and
gateways is also available to cater for access to the traditional services at the host
site or at remote locations.
 Optional is the 19” rack mounted expansion chassis or PIR (Port Interface Rack)
The PIR is available as a high density TDM gateway, and allows for the support of
traditional PBX packages such as for ISDN, Analogues and operator consoles.

1.3 UNIVERGE® SV8500 HERITAGE
The UNIVERGE® SV8500 system is the next step on the evolutionary path of the
UNIVERGE® SV7000 and the NEAX2400 systems, and it can be incorporated into networks
that contain either one or both of these products. Providing a totally set of around 800 features
and offering the intricate NEAX networking capabilities of CCIS and FCCS, the
UNIVERGE® SV8500 core software is based on the time proven and highly reliable software.
Although designed as a pure IP solution, the UNIVERGE® SV8500 may also be equipped to
accommodate traditional TDM digital and analogue ports. This is made possible with the
inclusion of high density TDM expansion chassis that supports many NEAX PBX packages.
This document provides a comprehensive overview of the SV8500 architecture including an
introduction into the technical characteristics of the system.
1.4 OVERVIEW OF THE UNIVERGE® SV8500
An NEC SV8500 implementation is a 3RU SV8500 server, but may also include up to 16
UNIVERGE® SV8500 8RU PIR’s.
The SV8500 server which is loaded with the main software, feature pack software and any
system software options also holds all of the licenses. It is the Telephony Processor for the
system handling all activities associated with IP Peer-to-Peer communications as well as the
traditional TDM telephones.
In addition to controlling all of the “Protocol handling” functions of the IP terminals and
trunks, it manages the communications between SIP devices/terminals and IP Peer-to-Peer or
TDM devices.
The SV8500 functions on an “open standard” Linux Operating System (O/S) which allows IP
based Telephony interconnection via a true client/server IP PBX design.
The SV8500 by using an “open standards” Linux platform leverages from the flexibility of
operating in a redundancy option configuration, to provide a reliable connection for IP
terminals, gateways and PC soft-phones.
NEC maintains an exceptionally high MTBF (Mean Time Between Failures) with this
platform by incorporating flash memory cards as opposed to hard disks as used in traditional
servers.

2. ADVANTAGES
2.1 THE HEART OF A GREAT SOLUTION
The NEC UNIVERGE® SV8500 is a “pure” client/server IP-PBX offering that provides
customers a full software generic feature package equal to those previously available only
with traditional circuit switched PBX systems.
The NEC SV8500 solution also provides the key features that typically all customers are
looking for;
 reliability,
 redundancy,
 survivability,
 terminal options
 an extensive range of telephony features
The SV8500 is a total communications system platform that consists of modular core and
optional hardware/software components. At the heart of the system is an IP-PBX based on a
true client/server design platform that does not require circuit switched common equipment
hardware for support of any analogue stations or trunk circuit requirements.
2.2 SCALABILITY OF THE UNIVERGE® SV8500
The NEC SV8500 has primarily been designed for customers who require a significant
percentage of their telephony equipment to be IP based for desktop and/or wireless.
The SV8500 is very easy to scale due to the simplicity of its build rules and licenses and
offers a per port growth path for its IP connectivity, with a maximum capacity in a stand alone
configuration of 6,144 ports. However, with the addition of the optional NEC Fusion software
(FCCS) a solution can be expanded for up to 192,000 ports in a feature transparent cluster.
If required a high density TDM gateway chassis (PIR) supporting up to a maximum of 384
ports can be deployed. Requiring one system capacity license per PIR, a single SV8500
system can have connected just one, or up to 16 PIR’s.
When utilizing a PIR, the relevant hardware interface packages will be required.
These packages are based on current interfaces being used in the NEC UNIVERGE® IPX
system and range from a 4 port to 32 port capacity depending on the functionality required.
2.3 SURVIVABILITY OF THE UNIVERGE® SV8500
The NEC SV8500 offers multiple levels of solution survivability. At the very top level it
offers hot standby host servers. The hot standby system mirrors the online host and provides a
full service to the LAN attached UNIVERGE desktop IP terminals, other IP terminals, IP
devices and high density TDM Gateways should the primary server fail.
The change over of online to standby server is virtually seamless with calls in progress
normally not affected.
The next level of survivability offered is the implementation of an alternative registration
server called an SR-MGC.
Typically deployed remotely from the host on a WAN, one or many SR-MGC servers can be
installed. Their implementation location would be dependant on redundancy levels required
and the overall network design.
IP Terminals and IP Gateways support multiple registration options and they can take
advantage of one or many SR-MGC’s should the network to the host be lost.

2.4 LEVERAGING WITH THE UNIVERGE® SV8500
NEC has a strong focus on supporting customers who have previously purchased their
products and consequently offer various options for backward compatibility.
 Many packages from the large ICS, IMX and IPX NEAX models of PBX can still
be used in the SV8500 high density TDM chassis (PIR).
 With regular software releases available for the NEC SV8500, it allows for
customers to gain access to all of the latest software version features, by
implementing a software upgrade.
 The SV8500 can support CCIS links to any other existing NEAX PBX systems that
support CCIS Trunking. This provides a strong level of user functionality and
feature transparency between the different models of NEC systems.
2.5 UNIVERGE® SV8500 SUPPORTED OPTIONS
The NEC UNIVERGE® SV8500 has a wide and varied range of integrated communications
software options, features, terminals and devices that it supports. This provides customers
with the capability to build extremely flexible and robust configurations and with the strength
to scale it to suit their immediate and future business needs.
More details of the specific software options supported on the SV8500 such as ACD, OAI,
CCIS, FCCS and Hospitality can be found further into this document.
The AES (128 bit) Encryption function is an additional security measure that is also an option
available to customers if desired.
2.6 UNIVERGE® SV8500 SYSTEM SOFTWARE UPGRADES
Major software versions for the SV8500 are being released periodically. These software
versions are not seen as a mandatory upgrade process for customers and are only required for
users looking at utilizing the additional and more recently incorporated features. Customers
can skip several software releases but are still able to upgrade to the very latest software level
if they have the appropriate hardware platform.
The NEC SV8500 system software can be loaded from a CD onto the system flash card. The
new software version is then updated in the SV8500 system with a system reset which can be
conducted at a time most convenient for the customer. A CPU reset for a typical system
would normally take between 10 and 40 seconds before the system is back online. The reset
time is still less than 2 minutes even for a very large system implementation.
2.7 UNIVERGE® SV8500 INTEGRAL HANDSET SUPPORT
The NEC SV8500 allows for the connection of UNIVERGE desktop IP terminals that use
NEC’s Extended SIP signaling. From a user perspective, the UNIVERGE desktop IP terminal
will operate similarly to that of a traditional UNIVERGE desktop digital terminal. This can
dramatically reduce implementation costs due to the limited requirement for staff training.
Hot-desking and individual operator security can be implemented simply by using the
UNIVERGE desktop IP extension log-on, log-off capability.
Significant network infrastructure savings can also be achieved by utilizing the additional PC
switch port connection available on the advanced UNIVERGE desktop IP extensions.
The NEC UNIVERGE desktop IP extension can be configured with up to four alternate server
addresses in order to cover WAN failure or loss of internet connectivity. The UNIVERGE
desktop IP extension will try each address in turn in an attempt to register to an active
SV8500 or SR-MGC.
To support a mobile workforce, the SV8500 also supports Voice over WLAN handsets
utilizing SIP protocols.

3. CAPABILITIES
3.1 UNIVERGE® SV8500 INTEROPERABILITY WITH PUBLIC
NETWORKS
The NEC SV8500 provides interface gateways to ISDN Primary Rate, Basic Rate, SIP Trunks
and to COT PSTN services. It provides for flexible managed least cost routing (LCR) of
incoming and outgoing calls with support for calling line identification (CLI) on both ISDN
and PSTN trunks with advice of charge (AOC) also available via ISDN.
The NEC SV8500 can also support a direct connection into a mobile carrier via either E1 link,
ISDN PRA, PSTN, SIP trunks or QSIG links.
For SIP trunk connectivity between customer equipment and the Carriers, there may be a
requirement for additional development depending on the SIP interoperability and
functionality required by the customer and the carrier network.
3.2 UNIVERGE® SV8500 ANALOGUE CONNECTIVITY
The NEC SV8500 offers many options for analogue connectivity.
For a concentrated deployment of analogue stations at the host site, up to 16 high density
chassis (PIR’s) can be provided. This allows up to 384 ports for a 8RU rack mount
configuration with the 8RU offering full common component redundancy. The appropriate 16
station or 24 station packages are then installed into the PIR as required.
Ethernet connected IP Media Converters are also available as either 4 ports or 8 ports. The
flexible use of a variety of media converters can be implemented throughout a single SV8500
solution.
3.3 UNIVERGE® SV8500 SIP CAPABILITY
From a terminal perspective, the NEC SV8500 supports both standards based RFC SIP and
also NEC Extended SIP. For a SIP terminal to operate on an SV8500 whether it is an NEC
UNIVERGE desktop IP Extensions and Softphone, a dedicated license per terminal is
required.
It should be noted that NEC standard SIP is based on the Version 2 IETF (RFC3261) SIP
specification and has been in development and testing since June 2003. Additional IETF SIP
draft and RFC documents are being created on a regular basis and NEC will be endeavoring
to support specifications relevant to the internetworking and functionality of their systems
well into the future.
NEC has also developed a range of SIP trunk Gateways. However SIP connectivity between
customer equipment and the Carriers may require additional development depending on the
SIP interoperability and functionality required by the customer and carrier network.
3.4 UNIVERGE® SV8500 TRAFFIC CAPABILITY
The SV8500 can provide a capability to handle approximately 1,000,000 Busy Hour Call
Attempt (BHCA) in the FCCS configuration.
12
UNIVERGE® SV8500 General Description
Version 5
3.5 UNIVERGE® SV8500 TDM CAPABILITY
With the introduction of VoIP and “Peer to Peer” functionality into the telephony market, we
now see changes in system relationships between hardware and terminals/trunks.
In a hybrid environment when deploying a PIR for traditional trunks or stations, there is
normally the requirement to provide for voice communication paths between the traditional
stations/services and the Pure IP stations/services. To allow this connectivity the SV8500 can
support the installation into the PIR of a device called an IP-PAD.
The IP-PAD when installed in the PIR allows for the conversion of TDM to IP and also IP to
TDM. Depending on your IP deployment requirements, there are different versions of IPPAD available which can allow for varying options including support for such features as
encryption and compression.
The number of IP-PAD circuits required in a system is based on traffic flow. Keeping this in
mind, each IP-PAD package is capable of handling up to 32 simultaneous calls.
For IP-PAD specifications and more details on the IP-PAD packages available, please go to
section 15 of this document.

5. HIGH DENSITY GATEWAYS
5.1 UNIVERGE® SV8500 HIGH DENSITY GATEWAYS
The unique design of the UNIVERGE® SV8500 high density gateways, also called a PIR
(Port Interface Rack) is based on the proven build and expandability of local modular units
called PIM’s (Port Interface Modules). This design provides great flexibility in system
configuration and easy cost effective growth. A PIR provides multiple universal card slots for
access to a maximum of 384 ports. The PIR’s are compact, 19” rack mounted units that
connect to the SV8500 for control and also out to external cabling frames via plug-in cables to
allow for terminals or trunk connection. Most general interface packages can be placed in any
PIR slot. This maximizes utilization of space and simplifies system set up.
Different PIR models (for SV7000) in the stacks cannot be mixed on a single SV8500 system.
5.2 THE 8RU HIGH DENSITY GATEWAY
The 8RU PIR is powered by the AC100v-240v or
DC48v.
This PIR offers 17 universal card slots allowing for
an extensive range of line and trunk card options as
well as providing dedicated special services card
slots for packages such as registers.
In addition, it accommodates with redundancy
options, TSW/MUX packages and DC-DC power
supply packages.
A single SV8500 system can support up to a
maximum of 16 8RU PIR’s.
By providing IP-PAD cards in the PIR it allows
connectivity between the TDM side and the IP
network side. (For details on the IP-PAD cards

6. IP MEDIA DEVICES
6.1 OVERVIEW
The SV8500 has the capability of supporting not just IP and SIP terminals but also a range of
IP and SIP Devices. These devices in most cases are common between the U-IPX and the
UNIVERGE® SV8500. This allows options for an IP deployment which can be on either a
single site LAN or over a National WAN. These devices include analogue Media Converters
(MC), PSTN and ISDN Media Gateways (MG) and voice conferencing servers (VS). Some
are available in a standalone box and others can be a provided as a blade that slots into a 1RU
19” rack mounted Multi Purpose Chassis (MPC).
6.2 ANALOGUE 8 PORT MC
The MC8 blade [SCA-8LCA] is an 8 port Media Converter (MC), providing media
converting function between Internet Protocol (LAN-side) and conventional Voice Data (MCconnected conventional terminal side). By using this converter, up to 8 analogue telephones
can serve as IP stations under the control of SV8500 system. Media Data (voice/ fax) is sent
and received directly between IP terminals (MC-to-MC, MC-to-UNIVERGE desktop IP
extensions, etc.) in Peer-to-Peer connection.
The 8MC Card comes with eight front accessible modular RJ45 jacks. Analogue telephones
or fax machines can be connected to these ports. The MC- connected terminals communicate
by directly sending conventional Media Data (voice/ fax) to the MC. The MC then embeds
the media into IP packets, which are sent to the destination IP terminals over the LAN/WAN.
The 8MC blades can mount in either side or both sides of a 1RU Multi Purpose Chassis.
With a 2nd 8MC blade mounted into a single MPC, the offering becomes a single 19” rack
mountable 1RU 16 port media converter.
6.3 ANALOGUE 4 PORT MC/2 PORT MG
The MCMG blade ［SCA-4LC2COT］is an 4 port Media convertor (MC) and 2 port Media
Gateway (MG).
The 4 port Media Converter (MC) is an interface providing media conversion between the
Internet Protocol (LAN-side) and conventional Voice Data (the MC connected terminal).
The 2 port Media Gateway (MG) is the interface between the Internet Protocol (LAN-side)
and the public carrier network (PSTN).
In an MC/MG device, the MC and MG functions can work together or independently.
This device, can in the case of power or Network failure, provide Power Failure Transfer
(PFT) which is the connection of the PSTN lines and Analogue terminals directly.
19
UNIVERGE® SV8500 General Description
Version 5
6.4 ISDN PRI MG
The ISDN Primary Rate Media Gateway (SCA-PRI) is an interface blade between the IP
network and with the public ISDN, and provides an efficient connection for up to 30 trunks
depending on the configuration of the SV8500.
A single SV8500 can support up to 32 MG-PRI Media Gateways.
Using an SV8500 solution programmed with LCR to control calls via SCA-PRI’s configured
in disbursed locations, short distance calls can be made over the WAN to the local ISDN
service, offering a cost-effective alternative network for hop-on and hop-off calls.
The SCA-PRI Media Gateway under control of the SV8500 can also act as a QSIG E1 trunk
interface into the IP network. In a similar process to setting up for ISDN, the QSIG trunks are
fully configurable from within the SV8500.
Once the SV8500 has route and trunk data programmed and the MG has been connected to
the IP network, it is then available as a QSIG E1 gateway.
6.5 CONFERENCE SERVER MG
The VS-32 Conference Server blade offers an Announcement feature, External Hold-Tone
feature, and multi party Conference Feature. Its main function is however for providing multi
party conference calls between IP stations and to IP devices for calls over the IP network
The VS-32 also provides the three-way Conference connection when required for UMS call
recording allowing the recording of the conversation between two parties.
When using a local MOH device, the cable for the external hold tone source needs to be an
all-purpose 3.5 monaural ear phone plug, which then fits directly into the music jack located
on the front of the VS-32.
As a remote deployment when a network failure occurs, the VS-32 Conference Server
continues to provide the Announcement feature, External Hold tone feature, and Conference
feature in conjunction with the activated remote survivable server (SR-MGC).
The VS-32 Conference Server allows for a customer to allocate the VS-32 Conference Server
features (Announcement / External Hold-Tone / Conference) within the guidelines as
indicated in the following chart:

6.6 SIP TRUNK MG
The Media Gateway-Session Initiation Protocol blade (SCA-16SIP) is an interface that
enables your system to build a multi-service and reliable Voice over IP (VoIP) network using
Session Initiation Protocol (SIP) defined by IETF. This SIP Media Gateway supports up to 16
trunks.
SIP is an application-layer control protocol that can initiate call setup, routing, authentication
and transferring other feature messages to endpoints.
* This blade is for specific country.
6.7 MULTI PURPOSE CHASSIS
For a concentration of Media Converter/Media Gateway options, a 1RU MPC (Multi Purpose
Chassis) can be installed into a standard 19” rack. This allows for either 1 or 2 of the MC/MG
cards or conference server blades to be installed. There is no restriction on the combination of
mounting blade types.
The UNIVERGE® SV8500 1U-MPC is 19-inch rack mountable.
It is designed for either 1 or 2 blades to be mounted in Slot #0/1.

7. APPLICATIONS
7.1 GENERAL
NEC offers a range of integrated application options all supported on the UNIVERGE®
SV8500 such as SMDR (call billing details), ACD (Automatic Call Distribution), OAI (Open
Application Interface), CCIS (Common Channel Interoffice Signaling), FCCS (Fusion Call
Control Signaling), ISDN (Integrated Services Digital Network), QSIG, P2P IP Trunking,
Hospitality and Healthcare Applications.
However NEC also understands that the strength of the SV8500 solution is significantly
enhanced with the use of third party applications. Many third party applications that are
supported from previous NEC PBX platforms can also function on to the SV8500. These
applications suites include,
 A range of call accounting applications for managing call billing
 Many Unified messaging and voice mail products, scaling from several users to
many thousands are also available to connect to the SV8500.
These are just a few of the many 3rd party developed application that provide real customer
benefits when purchasing an NEC solution.
7.2 OAI (OPEN APPLICATION INTERFACE)
The Open Application Interface (OAI) opens a whole new world of computer and
communication capabilities. The SV8500 and a general purpose computer are linked together
to provide an interactive system of unprecedented functionality. OAI is NEC’s evolutionary
advancement that enables a built-in processor to control the operation of the SV8500.
NEC’s OAI provides the tool to implement powerful integrated applications in which a
computer and communications facility function as an Integrated Communications System in
ways that have never before been possible. With the addition of the OAI software, control of
the system features is extended by the internal resident processor.
OAI permits an internal resident processor as an applications processor, to send instructions to
the SV8500 by allowing a two-way data exchange between the SV8500 CPU and the PC.
This brings about new operating efficiency which allows business staff to use their DT
terminals to communicate with the PC. The PC responds by updating the DT display in an
interactive format, or by sending information to other terminals, PCs, or DTs as instructed by
the application software. DT keypads can also be used to input data to the PC.
The control over integrated services and applications that OAI allows is surprisingly easy to
obtain. An existing PC with its current operating system can be used. OAI employs a standard
protocol conforming to the Open System Interconnection (OSI) model established by the
International Standards Organization (ISO). Therefore, OAI is compatible with most
computer systems, whether PC, micro, mini, or mainframe based.
OAI comes with a library of programs that translate standard programming instructions into
recognizable commands to the SV8500 processor.
Customized application programs can be written on a general purpose PC without reference to
the complex communication protocol proprietary to the SV8500 system.
7.3 MCI (MESSAGE CENTRE INTERFACE)
The key to successful business is the conveyance of accurate information and timely,
responsive action to internal and external communications. The voice messaging service
enables a business to operate in a precise manner, since accurate information is automatically
relayed.
23
UNIVERGE® SV8500 General Description
Version 5
Messaging System integration generally delivers the following major features.
 Call Forwarding to Personal Greeting
This allows callers to leave messages for subscribers who are busy or away form
their desks. Incoming calls routed to an unanswered or busy extension are
automatically forwarded directory to a subscriber’s voice mailbox.
 Message Waiting Indication
This will light a message-waiting lamp, activate a display, or provide a stutter dial
tone on the subscriber’s extension when new message have been received.
 Easy Message Access
This allows subscribers to retrieve new messages from their voice mailboxes
without entering a personal ID number. A security code may be required before
message playback to prevent unauthorized message access.
The SV8500 can provide voice messaging applications by integrating an external voice
messaging system via a Message Centre Interface (MCI).
This application may also be centralized in a CCIS or FCCS Network.
The MCI is an Ethernet data link operating under a specific message protocol and format. The
MCI can provide the following features.
 Sends incoming call information to an external voice messaging system, via the
MCI, when the voice messaging system answers.
 Controls messaging waiting lamps for stations based on information sent from the
voice messaging system.
7.4 SMDR (STATION MESSAGE DETAIL RECORD)
The Station Message Detail Record (SMDR) allows the UNIVERGE® SV8500 to record
detailed call information for all terminals over the system connected trunks
The SMDR data provides the call information on a per call basis.
The information generated includes:
 Calling station number or
 Trunk route number,
 Dialled number,
 Time to answer
 Call start time,
 Date and
 Call duration
The SMDR information is all compiled within the SV8500 CPU and then under the SV8500
control, outputs the call information as a real time information data stream to the collection
device via the Ethernet port.
During a LAN or WAN failure, or if the host SV8500 is offline and stations are operating off
an SR-MGC, then the SR-MGC will store the appropriate SMDR records. Once the LAN,
WAN or host SV8500 service is restored then the SR-MGC will down load the captured
SMDR stored details to the SV8500.
24
UNIVERGE® SV8500 General Description
Version 5
7.5 CONTACT CENTRE SOLUTIONS
ACD (Automatic Call Distribution)
The ACD software option can be an important inclusion to add to an SV8500 solution.
Contact Centre’s and telemarketers are able to take advantage of many new marketing
strategies involving customer service calls and consumer telephone sales. ACD can do this by
efficiently allocating calls to the available agents. It is not only important that a call be
captured, but that it should not wait longer than necessary. The ACD provides queuing and
levels of priority to ensure calls are handled in the order of arrival and importance.
The ACD evenly distributes customer calls by providing a queue for agents as well as for
callers. The call control and agent functions, when combined with an effective Management
Information System, are the tools to maximize profitability and efficiency.
There are many attributes that a true ACD must possess to provide cost effective handling of
customer traffic. Two basic features that distinguish an ACD are its ability to queue callers
when agents are not available and queue agents when callers are not available. This allows a
smooth and even distribution of work load and incoming traffic flow.
When all agents are busy and a call arrives, the ACD can control the length of time the caller
will hear ringing before the first announcement. The first announcement could be several
minutes or as short as two seconds and can be followed by Music-on-Hold and/or a second
announcement. During this time, a call may become eligible to be handled at an alternate
answering point.
Eligibility for overflow is possible as early as four seconds after the call has been detected.
When the call becomes eligible for overflow and the answering point is busy, the call will
queue in two places, the original queue and the overflow queue.
While calls are queuing, the agents can see the level of calls waiting as indicated by the call
waiting lamp at the agent’s position. The call waiting lamp has flexible thresh holds that can
be set to indicate the call status:
 Off: there are no calls in queue
 Illuminated: calls are in queue
 Flashing: a pre-programmed threshold has been exceeded
As calls increase and decrease in the queue, the lamp status will change to inform the agents
of the level of traffic at that moment.
When an agent becomes available at either answering point, the call is immediately routed to
that agent. If only a limited number of calls are to be allowed to queue, the queue length can
be adjusted. This feature provides an additional alternative for call handling based on traffic
loading.
To support the ACD agent’s efficiency, automatic answer and automatic release may be
utilized.
In the case of difficult callers or threatening calls, an emergency key may be used to request
assistance and simultaneously activate an emergency recorder.
If necessary, the supervisor, besides having all the same capabilities as an agent, also has the
ability to assist agents with difficult calls by invoking a monitor and record function.
The DT300/700 Series terminals when used for an ACD Agent have been specifically
designed for ACD operation and features, with the addition of strategically located ACD
functions buttons. The intelligent design provides the increased efficiency needed in a fast
paced call centre environment.
Headset and/or handset inbuilt modular jacks are incorporated into the DT300/700 Series
terminals and allow ACD Agent to accept either connection as standard.
The DT300/700 Series for ACD Agent also features a four/five-line by a 16-characters LCD
display that can identify the type of call by name or LDN (Listed Directory Number).

UNIVERGE® SV8500 General Description
Version 5
Q-Master
Residing on the Microsoft Windows operating environment, the Q-master has been designed
to take full advantage of the SV8500 OAI information, to combine the power and flexibility
of a LAN based CTI architecture. Q-Master can allow customization of contact centre
functionality to customer’s specific requirements. Call Centre Managers are able to adjust call
patterns, set skills based routing profiles and assign agents to multiple queues.
By utilizing incoming caller line identification (CLI), Q-Master determines where the call
originated and searches for a match in customer database. Key customers can automatically
be placed into priority queues, or directed to the agent who last dealt with that caller.
During periods of high traffic Q-Master greets callers with a series of announcements,
reassuring them that they have reached the right place and advising them of their position-inqueue. This encourages callers to stay on the line longer, significantly reducing call
abandonment rates.
Q-Master is fully modular in design, allowing contact centre managers to select the required
components to best meet their operational and budgetary objectives and their customer needs.
7.6 HOSPITALITY SOLUTIONS
The SV8500 through application software allows customizing to address the needs of the
hotel industry and has been the key to allow many hotels, rest homes, clinics, hospitals and
other lodging-oriented businesses to function more efficiently. From the small hotel requiring
basic services to the large hotel or hospital, the SV8500 offers sophisticated and enhanced
features to appease the five star expectations. The entire industry spectrum, from as few as
100 guest rooms to thousands, can be efficiently managed by a single SV8500.
Installations requiring remote administrative functions in multiple locations can also be
connected via NEC’s CCIS/FCCS networking feature or by Distributed IP devices.
The needs of the hotel administrative and guest environments have been surveyed, studied
and researched by NEC.
These needs have been specifically addressed by the unique and advanced hospitality-oriented
software exclusive to the UNIVERGE® SV8500 and U-IPX Hotel option.
The vast assortment of enhanced business features inherent in the SV8500 sophisticated
business software package have been incorporated and integrated into the Hotel system. With
this powerful software and the commitment of NEC to communications excellence, the
SV8500 can be a business passport to providing modern and efficient service to guests with
transparent ease of operations to the administration staff.
The following are descriptive summaries of just a few of the time and cost saving features
which are realized with the Hotel System software.
Language Services
The Language Service feature is a unique feature which provides personalized language
services to guests. Via the visual display on the console and incoming console keys, hotel
personnel are able to identify the guest’s language and answer appropriately. Guest station
calls may also be routed to a recorded announcement in the guest’s own language. Multiple
languages can be supported by a single system.
Guest Information Displays
Under PMS control, a guest’s name is displayed while ringing at selected administration
stations so that guests may receive a personal response when communicating with any special
administration service station. This feature is also equipped at the Hotel Console and
enhanced with a guest status display indicating such information as wake up time, message
waiting, VIP status, DND (do not disturb) status and room class. If required, a terminal can be
directed by the SV8500 to display enhanced guest information showing special administration
stations or attendant consoles additional information such as: name of all guests in room, date
of check-in/check-out, language, company/ division name and address.

Property Management System (PMS)
The SV8500 has been designed to accommodate the integration of an adjunct Property
Management System (PMS). The PMS allows the support and control of many front and back
office functions.
For example:
 Message Waiting Control
 Room/Housekeeping Status
 Room Change/Swap
 Check In/Out
 Connecting Room Service
 Directory Assistance Service (DAS)
Direct Data Entry
The SV8500 along with a Property Management System incorporates a Direct Data Entry
feature. This feature allows custom applications to be developed. A special access code and
up to 32 digits can be dialed from selected guest stations. These digits are sent to the PMS for
inventory control, mini-bar usage, maintenance, etc.

Class of Service and Station Message Detail Record (SMDR)
The sophisticated services of the SV8500, allows for the hotel staff to provide varying calling
privileges to staff members and guests. A guest’s Class of Service can be assigned upon
check-in, and the room automatically cut off from outbound calling upon check-out. Cost
effective services such as Least Cost Routing and Look Ahead Routing can be employed to
cut operating expenses. The Station Message Detail Record (SMDR) is provided as a real
time information data stream passed from the SV8500 to an adjunct call accounting package
to generate guest and staff call records and costs.
27
UNIVERGE® SV8500 General Description
Version 5
Emergency Call, Off Hook Alarm and Alert Services
These three features are included in the option software to provide hotel staff, guests and
property with added security in the event of an emergency.
 Emergency calling allows a selected administration display station to maintain a
connection even if the calling station hangs up; an event message can also be
generated to the system printer.
 An Off Hook Alarm will connect an inadvertently off hook station to a preselected
display telephone or Attendant Console so that appropriate action can be taken by
security personnel.
 Alert Services can be activated by the Attendant Console or selected special
administration stations, allowing the connection of all guest and special
administration stations in the SV8500 to recorded announcement trunks for the
relaying of emergency instructions.
7.7 Q-SIG SOLUTIONS
This feature enables the SV8500 to connect to other manufacturer systems as well as other

UNIVERGE® SV8500 General Description
Version 5
7.8 CCIS/FCCS OVERVIEW
NEC offers two very powerful networking options as either TDM or IP Peer to Peer.
The first is Common Channel Interoffice Signaling (CCIS) and the second is Fusion Call
Control Signaling (FCCS).
FCCS and CCIS are fully compatible. When a network consists of multiple trunk connections
to earlier generation systems, the connection will support the highest intelligence of feature
transparency and administrative capabilities of the earlier generation system.
CCIS provides a customer with enhanced feature transparency over tie line trunks and is fully
compatible with most other NEC NEAX systems. CCIS can be deployed between a mixture
of systems types, large and small, and over a variety of different types of connections.
When deploying the FCCS functional and intelligent network capability, it allows multiple
network nodes of U-IPX or UNIVERGE® SV8500 systems to be fully integrated creating one
logical network. This Network integration provides a customer with enhanced feature
transparency and strong centralized telecommunications functions.
FCCS also allows individual nodes dispersed within a network to operate as if each of them is
part of a single integrated PBX providing significant feature transparency and number
portability.
FCCS on the UNIVERGE® SV8500 is fully compatible with the U-IPX and may exist
between a mixture of these systems as IP peer-to-peer, point to multi-point trunks.
7.9 CCIS TRUNKING
The modular architecture and wide range of voice and data features available from an SV8500
have been developed with emphasis on continued enhancement within a single SV8500. In
order to meet the growing demand for further enhancement on a network level, NEC
developed a networking system employing Common Channel Interoffice Signaling (CCIS).
The CCIS trunking links together individual SV8500 systems (nodes) to form a transparent
voice and data network which acts as a single large SV8500, even though terminals within the
network are in fact connected to different SV8500’s. Common Channel Interoffice Signaling
(CCIS) derives its name from the fact that a signaling channel (link), separate from voice and
data channels, is provided between nodes for the sole purpose of signal exchange. This
signaling link is used in common by all voice and data links for exchange of information
relating to addressing (e.g. dialed digits, calling/called number); supervisory functions (e.g.
call setup and termination); and network accounting and management (e.g. centralized billing
and fault reporting.) This is unlike conventional tie line networks which exchange signaling
information over the same links as used for the voice transmission (Associated Channel
Interoffice Signaling).
Some advantages of the separate signaling link provided by CCIS over IP :
 Network Transparency
Because CCIS allows data relating to service features and station/trunk status to be
exchanged between nodes at a high rate of speed (64 Kbps), service is provided to all
users as though the CCIS network was a single SV8500.
 Centralized Facilities
Centralized Management: Fault messages from all nodes can be directed to one node.
Centralized Billing: Billing information for all nodes in the network can be processed
at one central location.
Centralized Attendant Service: Attendant services can be provided to multiple nodes
from one or more central location(s).

Version 5
Better Utilization of Trunking Facilities
Because network signaling is carried over separate signaling links, more efficient use
can be made for network trunks (reduced call holding time, reduced connection time,
etc.) so the number of trunk circuits required for a specified traffic capacity, may be
reduced.
Network Reliability
Alternate Routing provides the CCIS network with maximum reliability. If the
signaling link between two nodes should fail, signaling is sent over an alternate route,
via another node, without loss of service. Directly connected redundant links can also
be provided to assure reliability.
Reduction in Personnel
Because management, cost accounting, and services, such as Attendant operation, can
be centralized, efficient use can be made of the people necessary to administer the
network.
Reduced Hardware
Signaling over a common channel; better utilization of trunking facilities; and
centralized management and services all result in a vast reduction in hardware when a
CCIS network, rather than a conventional Tie line network, is used.
CCIS networks can be divided into the following types, depending upon the numbering plan
used: Main-Satellite Networks and Main-Remote/Campus Networks
Both networks provide uniformity of services throughout the CCIS network, and because of
numbering plan flexibility, station users are not conscious of the distance between nodes.


Main/Satellite Network (Opened Numbering):
In this type of network, offices are connected by means of a numbering plan
consisting of a three-digit office code, which denotes the location, and four-digit
station numbers.
Main-Remote/Campus Network (Closed Numbering):
In these types of networks, offices are connected by means of a numbering plan
consisting of four or five digit station numbers. The first one or two digit(s) of these
station numbers are used to denote the location. An advantage of this network is that
it is less complex and requires far less infrastructure than would be necessary if
traditional stations were connected to a single host system.

UNIVERGE® SV8500 General Description
Version 5
7.10 FCCS TRUNKING
The main advantage of using the Fusion Call Control Signaling (FCCS) system is improved
Inter-Office service feature functionality. The FCCS system eliminates the constraints
normally associated with network services that are offered using Common Channel InterOffice Signaling (CCIS) or Channel Associated Signaling (CAS).
The SV8500 supports FCCS to other SV8500 systems or to UNI-IPX systems with the
following benefits
 FCCS Networking via IP
This feature allows the system to exchange both Speech and FCCS Signals over an
Intranet. The Speech data between the IP Stations can be sent and received in a Peerto- Peer connection, while the control signals are handled by the System. The control
signals are all managed internally.

FCCS Alternate Routing - Backup
This feature automatically routes a FCCS over IP call over Alternate Routes when the
first-choice link is down due to the LAN failure, etc.

FCCS Location Diversity
This feature guarantees the reliability of the enterprise network connected by FCCS.
When a fault has occurred to a specific node within the FCCS network, IP terminals
accommodated in this faulty node automatically re-register to other nodes according
to the pre-assigned data. By receiving this request, other nodes within the FCCS
network back-up the call processing of DTs that were previously accommodated in
the faulty node, to avoid them being isolated from the network.
The Location Diversity feature is available for UNIVERGE desktop IP extensions and Dterm
SP30.
The number of primary stations + visitor stations should not exceed the total system capacity
licenses within each node. Additional System capacity licenses and Terminal licenses would
normally be required within each back-up node to allow for the terminals being recovered.
A system operating with FCCS allows the user to have telephone numbers in addition to
existing station numbers (Physical Station Numbers). The FCCS service features are activated
when a Telephone Number is dialed. The telephone number, which can be assigned on a
station basis, is a unique number within the FCCS network. If required, numbering plan data,
which is identical to that of an existing station number, can be used to maintain consistency of
the numbering plan. When this plan is adopted, you can use the same numbering plan data
after introducing the FCCS system.
An FCCS network has one Network Control Node (NCN) and the rest are Local Nodes (LN).
Multiple nodes cannot be assigned as a Network Control Node. The Network Control Node of
an FCCS network manages all of the other nodes on the network.
All nodes other than the Network Control Node are called Local Nodes. Fault information
generated at a Local Node is sent to the Network Control Node via an FCCS link, allowing
the Network Control Node to collect the fault information.
The PCPro is connected to the NCN. The PCPro manages the information from all nodes on
the network and has Network Data Memory that stores all of the data related to the network
level.
The telephone numbers are changed using the PCPro at the NCN and the PCPro also allows
the user to manage network-level office data.
An FCCS solution can have a maximum of 64 nodes and providing a total FCCS network
capability of 192,000 ports.

7.12 REMOTE NODE OVER IP SOLUTION (FOR NORTH AMERICA)
Building of an IP network has been spreading within the enterprise communication
environment in recent years. The IP Centrex model and the hot-desking model that were built
on this IP network have spread widely, too. These are the configurations which install a
control system in a main site, establish only an endpoint of an IP base at a remote site and
control the whole action from a main site.
However, since an endpoint's own cost isn't economical, continuing use of a TDM based
endpoint has been requested.
This means that mounting of analogue telephones and digital telephones may be requested at
the remote site.
If we receive such a situation, we can offer the feature which is called “Remote node over
IP.”

7.13 MIGRATION
We are offering a proposal that builds the latest communication environment by utilizing
some part of the existing infrastructure. We are calling this the “Migration Proposal”.
Our migration proposal makes it possible to utilize the UNIVERGE SV8500 within your
existing environment by utilizing parts of your existing communication property. By doing
this, the initial investment in the new technology will be partially suppressed.
Also, the amount of equipment which becomes unnecessary is minimized because
components of it can be reused. This restrains the effect of disposal of trash, which will have
a positive effect on our ecology activities.
The processing of waste from the Enterprise area has added to the environmental pollution in
recent years.

10. RELIABILITY & REDUNDANCY
10.1 SYSTEM RELIABILITY
System reliability is an established NEC hallmark, and the UNIVERGE® SV8500 continues
to offer the highest degree of secure system operation. A unique combination of flash upgrade
or EPROM for line, trunk, and common control circuit cards, plus Flash for generic system
software, provides customers with the traditional high level of reliability and security
Flash system memory provides:
 Easy program updates and upgrades.
Software upgrades are implemented by loading directly from flash cards
 Integrated Software Capabilities.
Unbundling of software allows organizations to choose Specific software
capabilities to suit their operational needs
10.2 UNIVERGE® SV8500 REDUNDANCY
The basic design philosophy of NEC is to provide redundant configurations (Dual), as a
customer selection option. The SV8500 system redundancy option comes in the form of a hot
standby capability.
The SV8500 system also extends its redundancy options to the 8RU PIR, which offers dual
packages for all critical circuitry such as TSW, MUX, Register package and AC/DC power.
The SV8500 System is able to employ non-redundant and redundant systems for processors,
memory, switching, bus, and power. In addition, it offers a wide selection of redundancy
options, which allows each system to be tailored to meet each customer’s specific requirement.
The options available are:
 Single system with No redundancy
 Dual PIR TSW and Power packages
 Dual PIR Power unit rectifiers
 Duplicated Gateways and Media Converters
NEC is able to offer this highly reliable system with some of the most comprehensive
redundancy options available with not only hardware support but also for the IP deployment.
SV8500’s showing connection points for hot Standby mode
Now with the primary support function of an SV8500 solution focusing on integrated IP
services, network failure redundancy is also a high priority and many options are available for
managing the range of IP devices hosted by an SV8500, but located remotely over a WAN.
This support service is provided by an SR-MGC (Server Remote Media Gateway Controller)
which offers IP WAN failure backup to the remotely installed IP stations and devices.
More details on the SR-MGC are available under “Remote survivability” in this documents.

10.3 UNIVERGE® SV8500 MTBF
The SV8500 “Mean Time Between Failure” (MTBF) figures reflect the true strength of
NEC’s product reliability with component failures expressed typically in terms of years.
The MTBF represents the minimum time frame in which a failure of any common equipment
such as processors, memory, switching, etc. may cause a partial system outage.
This is not to be confused with the Mean Time Between Catastrophic Failures (MTBCF),
where the system design provides for a minimum period of 20 years when implemented with
full redundancy.
The UNIVERGE® SV8500 has been tested to determine power requirements and the Mean
Time Between Failure (MTBF) for the various components.

11. REMOTE SURVIVABILITY
11.1 UNIVERGE® SV8500 REMOTE SURVIVABILITY
With the SV8500 capability of supporting WAN deployed IP stations and a range of IP
Devices, it now becomes extremely important to provide survivability options to remote
locations in the event of a WAN failure. To provide this option, the SV8500 supports the
implementation of a device called an SR-MGC (Survivable Remote Media Gateway
Controller)
The SR-MGC requires a license in the host SV8500 which is based on the capacity needs of
IP stations to be offered survivability. The SR-MGC models are available for a 50, 200, 500,
1000 and 2000 IP stations capacity. Specific quantities of IP deployed devices can also be
supported within the IP station capacity license.
In the event of a WAN failure, the SR-MGC allows for IP stations and IP devices that would
normally be connected over the WAN to the host SV8500 system, to register to it to maintain
call processing. The SR-MGC provides the IP stations with similar operational functionality
to that when hosted off the main system. If the IP stations normally access centralized hosted
services over the WAN, then this service may be affected until the WAN is restored.
When an SR-MGC is installed, it registers with the SV8500 server and requests a copy of all
relevant user information. Once all the information or office data has been downloaded from
the SV8500, it is then stored within the SR-MGC in non-volatile memory.
The customer data changes programmed at the SV8500 are then automatically transferred to
the SR-MGC on a daily basis. If required, changes to programming can also be uploaded to
the SR-MGC’s using a forced update command.
11.2 UNIVERGE® SV8500 SR-MGC (2U)
The 2RU SR-MGC has Licensing options available to backup either 200, 500, 1000 or 2000
stations. The 2RU SR-MGC provides survivability for SIP supported stations and devices as
well as the standard IP stations and devices
2RU SR-MGC
The number of SR-MGC’s that should be deployed in a network depends upon customer
needs and expectations. The different models of SR-MGC as described, can be licensed to a
single SV8500 host and the models can be selected to suite the necessary site requirements.
The SR-MGC’s could be deployed in various scenarios, for example one for an entire
network, one for every large office, one for each main building or one for every LAN within a
total WAN. This level of survivability is totally dependant upon the degree of concern that a
customer places on the redundancy option and what they feel comfortable with.

11.3 UNIVERGE® SV8500 SR-MGC (E)
The SR-MGC (E) is a new component in the lineup of SR-MGC models.
This SR-MGC (SR-MGC (E)) has downsized the chassis from 2U to 1.5U although it has
kept the same processing capability as the UNIVERGE SV8500. We have achieved cutting
the power consumption by approx. 50% compare to the 2U model. Also, we have
accomplished high speed file transfer between UNIVERGE SV8500 and the SR-MGC (E) so
we have reduced the amount of time for copying the office data compared to the 2U model.
The SR-MGC (E) also has Licensing options available to backup either 200, 500, 1000 or
2000 stations. And we have added 50 and 100 stations backup as well. The SR-MGC (E)
provides survivability for SIP supported stations and devices as well as the standard IP
stations and devices

12. SECURITY
12.1 ENCRYPTION
The Authentication and Encryption feature allows customers to provide a highly secure
network for their users. This is accomplished by Terminal Authentication, SIP Call Control
Signal Encryption, and RTP (Voice) Encryption of both SIP and UNIVERGE desktop IP
extensions.
The advantages of NEC VoIP Encryption are as follows:
 No need for digital certificates
Digital Certificates are not required for the Authentication.
 Easy Installation
Installation procedure requires a one-time password (used temporarily) registration
to the terminal and the system.
 High Authentication Level by Mutual Authentication
Terminal Authentication for preventing terminal spoofing and High Mutual
Authentication for preventing server spoofing.
 Adopting UDP for signal encryption to reduce the server load
TLS uses TCP, so 10 times more processing capability is required for the server to
control the same traffic.
This feature encrypts RTP packets and control signals (including passwords, login
accounts, and encryption keys) over IP networks. To use this feature, the terminal
will login with a one-time password to enable the security protocols. After Login,
128-bit AES encryption keys are applied to secure user information.
The RTP voice packets are only encrypted on the IP network. The connections to the PSTN
are left un-encrypted to comply with Federal regulations. RTP passing through a media
gateway or IP PAD will be unencrypted as it leaves the VoIP network. If one of the two
terminals used in a call does not support this feature, then the voice packet will not be
encrypted. If an encrypted call is transferred and the forwarding extensions support the
encryption, then the forwarded call is encrypted. When a forwarding extension does not
support the encryption, the forwarded call is left unencrypted.
When the three-way call feature is used, which includes phone recording and conference calls,
encrypted capability for the telephone call depends upon whether or not the station setting up
the conference supports encryption.
12.2 SECURITY STANDARD 802.1X
A more recent trend in enterprise network security, dictates that every IP device when
connecting to an Ethernet network will need to authenticate to the network before any access
is granted.
A LAN security standard, IEEE 802.1X Port-Based Network Access Control is increasingly
being adopted by enterprises worldwide to protect the data network. With the advent of VoIP,
it is anticipated that IP phones which connect to the Ethernet LAN, should be able to operate
under the 802.1X regime to maintain enterprise LAN security.
Therefore it is increasingly important for IP phones to be able to either authenticate itself via
802.1X or other mechanism to gain network access. The longer term view is to build 802.1X
Supplicant support directly onto the NEC UNIVERGE desktop IP extensions.
46
UNIVERGE® SV8500 General Description
Version 5
Currently however, the NEC IP Dterms have firmware onboard that allows 802.1X EAPOL
packet pass through. The “802.1X EAPOL” (Extensible Authentication Protocol over LAN)
pass-through is the basic method for an IP phone to operate in an 802.1X environment. In this
scenario, the IP phone itself actually does not authenticate to the switch, it simply passes the
EAPOL packets (the 802.1X authentication packets) from the connected PC to the Ethernet
switch.
The 802.1X supplicant is also supported but is dependant on the terminal firmware version.
12.3 PC PORT SHUTDOWN
A feature available on the NEC DT700 series is to allow control and management of the PC
port at the base of the DT700 series. The configuration in the system is done at 2 levels, at the
Administration Terminal and locally on the menu of the UNIVERGE desktop IP extensions.
In the case of a device that is connected via the PC port and it is infected with a virus, this
feature can disconnect the infected device from the Network.
The PC port shutdown feature is also supported on the NEC UNIVERGE desktop IP
extensions when loaded with SIP firmware and operating in a SIP environment.

13. MANAGEMENT
13.1 INTRODUCTION
The UNIVERGE® SV8500 employs the following advanced technologies to enhance
installation and maintenance functions
 Flash card Memory. The Flash system facilitates a one person operation of software
upgrades
 Viewing of card switch settings allowing cards with switch settings to be viewed
from the PC maintenance terminal
 
Supports individual packages with a display of their port and alarm status
 
Provides SNMP alarm output management options
13.2 UNIVERGE® SV8500 DATABASE INFORMATION
The NEC SV8500 uses internal proprietary program files to store customer configuration
information. This method allows for a simple and fast access for changes and backups.
These files can be readily accessed and changed via external management systems such as the
MA4000. The MA4000 keeps a synchronized SQL database of the SV8500 configuration at
all times and can be used to make changes to this SV8500 data. For additional efficiency and
automation, changes via the MA4000 can leverage additional interface such as CSV file.
Maintenance personnel can also interface with the system using the Maintenance
Administration Terminal (PCPro) from on-site or from a remote location to determine the
overall system status or to conduct system changes. System commands allow for the
programming and diagnostics of both traditional or IP terminals, trunks and devices.
13.3 MAINTENANCE ADMINISTRATION TERMINAL (PCPRO)
The management interface to the SV8500 can be performed by special software loaded onto a
PC known as the Maintenance Administration Terminal (PCPro). The PCPro run on a
selected Windows based PC and supports the following functions:
 System office data management (moves and changes)
 System office data downloads / backups to flash card
 Traffic data display
 System Message display
The PCPro also provides access to a variety of traffic management reports to be used for
overall analysis of system performance. It is used to request and display the type of report,
measurement time period and time increments of reports. Traffic reports can be produced by
assignment which will provide such information as:
 Terminal Traffic
 Route Traffic
 Station Peg Counts
 Attendant Console Peg Counts
 Route Peg Counts
 Service Feature Peg Counts
 UCD Route Peg Counts
 UCD Group Peg Counts
 UCD Station Peg Counts
48
UNIVERGE® SV8500 General Description
Version 5
The SV8500 diagnostics software constantly monitors the operating system and automatically
generates supervision and control fault information on the overall system performance. The
information is then passed of to the PCPro or to remote monitoring equipment. This alarm
information can also be processed as SNMP.
The UNIVERGE® SV8500 can also be connected in a network of UNI-IPX systems running
FCCS (Fusion Call Control Signaling). A centralized Maintenance Terminal is connected to
the master control node (NCN) for management of all of the systems within the network.

The NEC SV8500 has several options and change levels available for the system
administration. The high level management interface is controlled via an IP connected
Terminal. It offers multiple levels of access via passwords and is generally used for the
detailed technical configuration of a solution.
The NEC SV8500 can also be managed with the MA4000 web based maintenance tool,
allowing an end user to configure and manage multiple PBX’s via a simple-to-use web based
tool. The tool is built with the IT manager in mind, facilitating:
 Web based deployment, meaning no additional software is required on the client
machine, can be accessed from anywhere on the corporate LAN / WAN.
 Fully configurable security allowing user access to be controlled down to the
smallest feature.
 Complete auditing, with every change logged, time stamped and recorded against a
user.
 Scheduled backup can be performed allowing for complete networks of PBX’s to be
centrally maintained.
 Date and time synchronization done automatically.
13.5 UNIVERGE® SV8500 SYSTEM ADMINISTRATION
The NEC SV8500 administration terminal (PCPro), although the primary tool for
implementing detailed system moves and changes, also has the capability to record and
display alarms, display CPU performance, track call trace information, record traffic
information and trunk utilization.
Alternatively the MA4000 can be used. The MA4000 is a web based maintenance tool
allowing an end user to access multiple systems via a simple to use web based interface.
This tool has many useful functions, including:
 Web based deployment.
 Fully configurable security.
 Complete auditing.
 Any change (or batch of changes) can be executed at once or scheduled to be
performed at any time, with a complete roll back in case of errors. With changes as
complex as for every extension who’s users name contains an ‘e’, set line key 3 to
‘log-out’ and update the name display.
 Scheduled backup and restoration can be performed allowing for complete networks
of PBX’s to be centrally maintained.
 Date and time synchronization done automatically.

13.6 SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP one of the network management protocols defined by IETF, transfers and controls
information on the TCP/IP basis between the SNMP manager and the SNMP agent.
Generally, SNMP management software such as HP Open View needs to be installed in the
SNMP manager, and operated to monitor the agents. On the other side, the SNMP agent
collects network information and stores it as Management Information Base (MIB), which the
SNMP manager can control.
This system supports MIB-II based on RFC1158 and RFC1213.
This setting provides the following functions:
-SNMP manager gets/sets MIB information of SNMP agent.
-SNMP manager monitors/clears the alarms for SNMP agent.
-SNMP agent sends trap (fault information) to SNMP manager.
Other than standard MIB-II, the system supports NEC-specific MIB.
Supports MIB information (GET) listed below.
• Alarm Lamp Status
• MAJOR Lamp Status
• MINOR Lamp Status
• Supervisory Status
• CPU Usage

13.7 VOICE QUALITY MANAGEMENT
The SV8500 incorporates various features to provide high voice quality as well as to monitor
voice quality in the system. The items below illustrate some of the features that can be
utilized by a customer.
Feature R-58 (RTP Information Output) collects information related to low voice quality or
an abnormal status of IP devices and then outputs that information to a log file. The
information can then be used by a network administrator to debug devices and/or the network.
The log can be output by using SNMP manager and PCPro.
This feature provides the following capability:
 Communication Log Collection: A history (includes speech time, opponent, IP
Address, MAC Address and Voice Quality) per speech is collected and output.
 Failure Log Collection: Reset factor and Time of occurrence are output.
Sending/receiving times and Retransmission times are collected.
When a system administrator receives voice quality complaints from an end user, the related
data can be extracted from the communication log and fault logs to determine the cause of
that voice quality.
With the Terminal Claim Handling for IP terminals feature (T-65), individual users (stations)
can send notices about real or perceived voice quality problems to the system administrator.
The system administrator uses the call quality information and feature R-58 to review the case
and determine if the problem is related to the network, a portion of the network, a particular
IP device, or the user themselves.
This operation is also available on UNIVERGE desktop IP extensions (DT700 series). During
the call, the users will need to push the info button on their terminal where they can select
several call attributes about the current call. The information is then captured in an SNMP
TRAP message.
The feature is available on the following terminals:
 IP enabled Dterm / Dterm Series E / Dterm Series i with LCD
 UNIVERGE desktop IP extensions (DT700 Series) with LCD
 Dterm Softphone (using the Function key)
The following attributes can be selected about the voice call quality. These answers are sent to
the system administrator:
 No sound (Yes/No)
 Echo (Yes/No)
 Broken sound (Yes/No)
 Noise (Yes/No)
●
Delay (Yes/No)
 Low/High volume (Yes/No)
 One-way communication (Yes/No)
 Distortion (Yes/No)

Total amount of System Capacity = a + b + c + d + e + f + g + i + j + k + l + m + n
e.g. SCA-4LC2COT/1, DT700/340
Total amount of System Capacity = b(4) + e(340) + i(2) + m+ n
=> 8(minimum unit: 8) + 344(minimum unit: 8) + 8(minimum unit: 8) + m + n
=> 360 (ports) + m + n (“m + n” is depends on single/dual)
Note 1:
Each group of 3 terminals, an extra port is needed (i.e. it is necessary to reserve ports for
WLAN Handset and 3rd party SIP terminals in blocks of 4 ports).
So in the example above this would mean:
- For 1 x WLAN Handset and 1 x 3rd Party SIP terminal: 4 ports
- For 2 x WLAN Handset and 3 x 3rd Party SIP terminals: 8 ports
One Virtual IP-BS can handle the mix of WLAN Handset and 3rd Party SIP terminal.
You need twice the port for the dual system.
Note 2:
Maximum accommodating number of MG-PRI (SCA-30PRIA) in the system is 32.
Note 3:
Each component belongs group of “a” to “l”. Each group (“a” to “l”) has “Minimum

14.6 ENVIRONMENTAL REQUIREMENTS
The SV8500 is sensitive to increases in temperature and humidity, as is a computer. Air
conditioning may be required. The following details address the environmental conditions for
operating temperature and humidity.
The table below shows the environmental conditions that are required in the equipment room.
If the system is operated in an environment that does not meet these specifications, the
reliability of the equipment may be impaired. Improper operating conditions can cause circuit
boards, etc. to deteriorate. Therefore, to enable the equipment to operate to the full extent of its
expected lifetime, give careful consideration to the location of the equipment and to proper
ventilation and air conditioning. If the temperature or humidity fluctuates repeatedly, the
system’s electronic parts can be adversely affected. Such conditions will promote the
corrosion of metal parts and the deterioration of insulation, thereby lowering the overall
reliability of the system.
Environmental Requirements
 Temperature: 0°C~40°C (32°F~104°F)
 Humidity: 20%~85% (not condensing)
 Main Source Power: AC100/120/230/240V ±10% 50/60 Hz
Do not install an SV8500 in inappropriate locations as it could cause operational failures or
electrical shock. Locations such as on an unstable floor, in areas that may be subjected to dust,
water, oil or chemicals, in direct sunlight, in locations that receive strong electric waves from
other equipment or areas receiving possible vibration.
The installation location of the SV8500 servers and devices is important and also must be
considered so as to not interfere with heat liberation and ventilation.
The UNIVERGE® SV8500 Servers and Remote Devices operate from a commercial power,
however it is recommended to use a UPS for the Servers as well as the Gateways and Media
Converters for a more reliable operation.
In the case of an implementation utilizing 8RU PIR’s then their primary operating supply of
48v is provided by 1RU rectifiers which itself connects into a commercial power. In this
instance it is also recommended to use some form of back power or UPS for the rectifiers.
